Answer:

See below ↓↓

Step-by-step explanation:

a₁ refers to the first term of the sequence.

That is clearly : a₁ = 6

The formula for the nth term is :

aₙ = a₁rⁿ⁻¹
Common ratio (r) = quotient of consecutive terms
r = -12/6 = -2

Therefore, the nth term is :

aₙ = 6(-2)ⁿ⁻¹

Daisy spent a total of $31 before tax on ice cream. the table below shows the different flavors she bought. a carton of strawber

notsponge [240]

The cost of 1 vanilla ice cream and 1 strawberry ice cream should total to $31. Since you only bought one of each flavor, you simply have to add their unit prices.

Cost for 1 carton of strawberry ice cream + Cost for 1 carton of vanilla ice cream = Total Cost
Total Cost = s + v --> this is the general equation

Since s = 1.5 + v, the modified equation would be
Total Cost = 1.5 + v + v
Total Cost = 1.5 + 2v
